Patented Aug. 8, 1933 ears rr orri' STENEIL PRINTING AND COPYING MACHINE This invention relates to stencils which are used extensively to address envelopes, letters, and the like; and to printing machines involving the use of such stencils.

There are at present two different types of stencils or printing devices in extensive use.

One type of device is relatively flexible and cone sists of a paper frame having a window therein occupied by a piece of stencil paper which bears the address or other data to be printed, the paper being imperforate except at the address-impressions and ink being forced through the impressions inthe act of printing. The other type of stencil or printing device is relatively rigid and consists of a metal plate having the characters comprising the address embossed therein, the plate being carried by a rigid metal frame and the printing being effected by pressing the cmbossed plate upon an ink ribbon-and thus pressing the ribbon upon the sheet to be printed and eiiecting the printing thereon.

t is frequently desirable for the user or" one type or printing device to adopt the other type of printing device. Since a single user, however, may have thousands of printing devices in his collection, all having different addresses, and

since the printing devi es ofttimes are also used as index cards as an aid to the users bookkeeping system, it oittinies amount. of work and expense to make out a 001- lection of one type of printing device prior to' discarding the previously'used type of printing device; Consequently, an object of the present invention is the provision of an apparatus which is capable of utilizing one type of printing device to transfer its record tothe othertype of printing device.

The collection of printing devices is usually retained in a predetermined, as alphabetical, or classified, order. Consequently, it is a further object of thisinvention to providethe apparatus with means by which the printing devices of the type to be discarded form the addresses or equivalent on the different type of printing devices to be adopted and collect the latter devices in the same order in which the devices to be discarded,

are arranged.

A further object of the invention is the provision of a stenoihcopying .machine wherein all address-bearing printing devices representing one type are caused to form or copy their adinvolves a considerable improve upon stencil forming machines and methods.

Thetwo types of printing devices with whichthe present invention is concerned are illustrated in Figs. 14 and 15.

The stencil illustrated in Fig. 15. which is representative of what is herein termed the flexible type of stencil consists of a rectangular pape' frame 20 having a Window 22 therein and a peripheral ledge 24 around the window on which a sheet 26 of stencil paper is secured, the sheet overlying the window. The sheet is compcsed usually of strong porous paper having a coating of -a gelatinous material thereon'which' is adapted to be out through by the applicationof a suitable type character to expose the porous paper under the cut regions thereby to formthe stencil characters 28, which may consist of an address. When ink is applied to said stencil sheet by a roller, the ink is forced through the cut portions of the gelatinous coating and through the porous paper therebeneath and onto the sheet or article to be printed, thereby leaving 7 an ink record of the characters borne by the stencil. The printing device illustrated in Fig. 14, is representative of what is herein termed the rigid type of stencil or printing plate and includes a metal plate 30, which plate is enlbossed by type characters to present raised printing portions 32, see especially Fig. 12, on one face thereof which are duplicates of the type characters and in themselves function as type. The plate is adapted to force an inked ribbon against the sheet to be printed and thereby records an im pression of the embossed characters 32 on the sheet where the ribbon forcibly engages it. The stencil plate 30 is carried by a rigid metal frame 34. While the address borne by the flexible type of stencil can be read directly from the reverse side of the stencil, this can not be done with the rigid type of printing device; and the characters of the obverse side or working face thereof are reversed so that they can only be read with difliculty. Consequently, the frame 3% usually also carries a paper sheet 36 which bears a duplicate of the address carried by the plate.

The present invention is. concerned in its most specific application, with forming on the flexible stencil, by means of the rigid stencil, the address borne .by the rigid printing plate.

The machine constructed in accordance with the present invention has holders and guideways for both types of printing devices and means so arranged that pressure is applied to two superimposed rigid and flexible printing devices to cause the address characters of the rigid type of printing plate to cut through the gelatinous coating of the flexible stencil and thereby transfer its impression to the flexible stencil and form the stencil so that the impressed address can be used for printing.

The machine includes the frame 38 which supports the rectangular table 40. A pair of spaced rails 42 having opposed stencil-receiving grooves are located above and are extended lengthwise of the table, and constitute a stencil track along and in the grooves of which successive flexible stencils are caused to be moved from one end to the other thereof. A stencil holder 44 is disposed at the right hand end of the stencil track, see

Figs. 1 and 3, and is extended upwardly thereabove and is adapted to support a pile of superimposed flexible stencils. The lowermost stencils are moved in successive order from the pile in the holder and into and along the track and into and out of a printing or copying position therein and into a stencil receiver by a pusher 46 which is shown in perspective in l6 and which is reciprocated in. the direction. of the 60" length of the track under the stencil holder and into engagement with the successive lowermost stencils thereof. The particular construction of the pusher is not herein of particular consequence.

The pusher is reciprocated by means of a connecting rod 48 which is pivotally connected there,-

to and to a crank arm 50 fixed to the upper end of a vertically rotatable shaft 52 that is geared bybevel gears 54 of equal diameter to the shaf 56 of a power mechanism 58 which is well known inthe art and need not be further described. Said mechanism is driven by a pulley 57 and the driving connection between it and the output sic of the mechanism is under control of a treadle the rotation of the shaft 56 and also the operation of the impression means presently to be described. As thus arranged, each complete rotation of the shaft 56 causes a complete reciprocatory movement of the stencil pusher.

After the flexible stencils have been moved along the track into and out of a printing or copying position intermediate the ends of said track they are moved into a stencil elevating mechanism 60 which serves to raise the stencils and to deliver them into a stencil receiver 62. Said stencil raising mechanism includes a pair of side plates 64 which are spaced apart lengthwise of the stencil track and have arcuate grooves 66, see especially Fig. 2, therein into which the opposite ends of the stencils are adapted to be located. A rotatable shaft 68 carries a pair of arms 70 which engage a side edge of the stencil and move it upwardly along said arcuate groove 66 and into the spiral grooves '72 of elevating worms 76 that are disposed in communication with the upper ends of said grooves 66. Said worms serve to raise the stencil upwardly and to position it at the bottom of the pile of stencils in the holder 62. The worms also constitute the supporting for the pile of stencils therein. The worms are geared to the shaft 68 by bevel gears '78. Said shaft is driven by a chain 80 from drive shaft 82 and at the same speed therewith. Said shaft 82 is driven by a chain 84 from and at the speed of the shaft 56 of the power mechanism so that both the elevating mechanism and the stencil pusher positively operate in relation with each other. The elevating mechanism and the elevated stencil holder 62 are in themselves old the art can be constructed, for example, as shown in the Sterling Elliott Patent No. 1,210,440, dated January 2, 1917.

The mechanism thus described operates to move successive flexible stencils from one holder to the other and into and out of copying position and to hold them momentarily stationary in copying position during the return stroke of the stencil pusher.

The rigid printing plates are guided for movement under the flexible stencils in a line at right angles thereto. The rigid plates are moved along a guide frame 86, see Figs. 2, 3' and 6, which is secured by ears 88 to the underside of the table 40 under a transversely-elongated opening therein. The frame 86 consists of a pair of guide members 90 connected by one or more integral cross bars 92 having opposed seats 94 on which the frames 34 of the plates are supported and moved. A holder 96 for the plates is disposed above the rear end of the guide frame and is adapted to hold a pile of superimposed plates.

The feeding means for the printing plates includes a reciprocating frame having a pair of spaced connected side bars 98 which are slidably received in grooves 100 of the guide frame 90. Said bars are provided with a plurality of forwardly extended spring-urged dogs 102 which are adapted to engage the rearedges of the plates in the guide frame as shown in Figs. 2 and 5 and move the plates forwardly as the frame. is moved forwardly and to pass under the plates as the frame is moved rearwardly. The guide frame for the plates extends immediately under the stencil track for the flexible stencils as is illustrated particularly in Figs. 4 and 12, and the printing plates are adapted to be stationary therein while the feeding frame is being reciprocated rearwardly, thereby to permit the printing or copying operation of the printing plate on a flexible stencil. The plates are moved forwardly beyond the aforesaid printing position and are deposited on a-movable conveyor belt 104 where they are conveyed away from the machine and can-be collected in a receptacle 105, to be subsequently retained or discarded.

The guide frame 86 is provided with a solid transverse member 106,,see Figs. 2,4, and 12, which underlies the printing plates when they are in printing position beneath the track for the flexible stencils and constitutes a-platen 'or' anvil which supports them rigidly, against the pressure of the printing or embossing mechanism hereinafter to be described. The construction of the holders and guiding and feeding mechanism for the printing plates is or can be common in the art.

The feeding frame for the printing plates is operated by mechanism which includes a link 108 pivotally connected to a rod 110 extended'between ears 112 that depend below the side bars 98. Said link is extended rearwardly, and is pivotally connected with the upper end of a generally vertical lever 114 which is pivoted at its lower end on a pin 116 carried by a depending bracket or stirrup 1180f the guide frame 86.,

- and is reciprocated by the power mechanism 58 in a well known manner and is so timed with.

respect to the operation of the shaft 56 of the power mechanism that both the rigid and flexible printing devices are'moved forwardly from their respective holders in unison.

The belt 104 is advanced in a step-by-step manner in one direction by a pawl arm 105 which is pivoted on the belt-supporting shaft 107 and has a spring-urged pawl 109 which engages a ratchet 111 fixed to said shaft. a pin and slot connection 113 with an arm 115 fixed to the reciprocatory shaft 124 such that each reciprocatory movement thereof ,in one direction advances the belt by a distance that is somewhat greater than the length of a flexible stencil. l

Mechanism is provided to urge two superposed printing devices into forcible engagement whenthey are in copying position whereby to cause'the embossed characters carried by the printing plate to cut through the gelatinous coating of. thestencil and-thereby form the printing characters of the plate in the stencil, whereby to condition it for printing such characters. The mechanisinto accomplish this result includes a roll 130 which is disposed between the rails 42 of the track for the stencils and is movable lengthwise of said track in pressure-applying engagement with the stencils therein. The length of the. roller is somewhat less than the width of the window 22 in the sten oil so that the roller engages only the stencil sheet 26 of the stencil. The roller is made of hard metal, as steel, and the surface thereof preferably is knurled to provide a series of points of projections being so closely spaced, or the knurling being so fine, that it cannot be clearly illustrated herein. 7

The roll is mounted between and is rotatably supported in the forks 132 of a frame'134 which is connected by a rod 136, which is adjustable as to Said arm has length, to a cross bar 138 which is located between and pivoted to the upper ends of spaced arms 140 that constitute angoperating frame for reciproeating the roller. .Said arms are pivoted intermediate their ends to a bracket 142 depending from the table. Said frame is connected by a connecting rod 144 that is pivotally connected to the lower ends of said arms to a crank pin 146 carried by a'horizontally rotatable gear 148 journalled in the bracket 150. Said gear is driven at half speed by a pinion gear 152 fixed to the shaft, 52. The radial line between the crank pin 146 and the axis of the gear 148 is displaced approximately 45 with respect to the crank arm 150 that operates the stencil pusher, in the setting of the parts illustrated in Fig.1. With this arrangement, the roller 130 is caused to roll over the stencils only while the pusher is moving backward, or to the right, Fig. 1, and remains beyond the position occupied bythe stencils, at one end or the other thereof, when the pusher is moving forwardly to deliver a new stencil into printing position. The periods of rest or inactivity of the roller are obtained when the gear 148 is moving the crank pin 146 across dead center, on both sides of the gear. While the roller is .not actually motionless, at such times, its extent of movement is so small that it does not come into engagement with a moving stencil. The extent of dead-center movement of the gear 148 is approximately Mechanism is provided to hold the roll in pressure applying relation with the two printing devices and also to cause the roll to move upwardly above thedevices as it moves beyond both endst-.ereof so that the devices can then move freely in their tracks. Said mechanism includes a pair. of upstanding horizontal plates 160 which are extended lengthwise of the stencil track 42 onopposite sides thereof and are fixed to the table 40 by thebolts 162. Cam bars 164 are carried by said plates, on the confronting faces thereof, and have cam grooves therein which have horizontal sections 172 and elevated dwell sections 174 at the the other of the printing position, the cam rollers 176 are inthe elevated dwell portions 174 of the bars and the roll is elevated into a position above and out of contact with the flexible stencils, and beyond the ends'of the stencils, or at least beyond the address-portions thereofu When the roll is moved across the printing position, the cam rolls 1'76 engage and ride over the cam faces 172 of said bars and consequently the roll132 is depressed to force the flexible stencil into pressureapplying engagement with the printing plate, as illustrated in Fig. 12, the stencil sheet of the flexi ble stencil being flexed between its frame to permit such engagement. The pressure exerted by the roll 130 between the two printing devices is adapted to be suiiicient to cause the embossed characters of the'printing plate to cut through the gelatinous coating of the stencil and thereby transfer its address to the stencil. The knurl ing of the roll 130'facilitates this operation as it 1 increases the unit pressure between the stencils at the points of contact. The knurling is also important in that it prevents the complete severing of the material within the outline of the letter F from the body of the stencil sheet, which mate-.

rial, in letters like 0, D, for instance, might otherwise drop out of the body of the stencil sheet. By causing the roll to move lengthwise of the stencil, the stencil is caused to engage but few areas of the type characters of the printing plate at a time so that strong unit pressurecan be obtained to effect the transferring operation. It will be appreciated that the two types of printing devices are moved in their guideways in such manner that the length of the stencil extends lengthwise of the address carried by the printing plate.

The various steps in the transferring operation are illustrated in'Figs. 8 through 11 inclusive. Fig. 8 illustrates the position of a flexible stencil, the impression roller and the pusher for the flexible stencil at the time the pusher is at the extreme end of its operating stroke and has moveda stencil into printing position to the left of the impression roll 130. The pusher then moves backwardly or to the right and the roll moves to the left over and in pressure applying engagement with the stencil and into a position beyond and above the stencil and at the left thereof. The pusher makes a second operative stroke and pushes a second stencil into position, the feeding mechanism for the rigid printing plates being also at the same time moving a plateinto position under a stencil. During this movement, the impression roll remains stationary. The pusher then returns to the right and the impression roll also moves to the right and rolls over the into engagement with the stencil, thus cutting into the stencil, the addressed data carried by the printing plate. The impression roll moves in opposite directions in engagement with alternate flexible stencils.

With this machine, the stencils are out and deposited in the stencil holder in the same order that the printing plates are presented to the printing position that the addresses borne by the printing plate collection are transferred to the collection of stencils without disarranging the order in which the addresses appear in the collection.
